REFRIGERATOR.

Application filed January 4, 1926 Serial No. 79,089.

This invention is applicable to refrigerators of any size but is more particularly valuable in connection with refrigerators of the larger sizes, and objects of the invention are, to prevent warm air pockets; to give the cold air currents the. most effective direction; to make the most'convenient and effective disposal of the water produced by the melting ice; to minimize accumulations of mo sture on the walls and other surfaces; to minimize the surfaces on which suchaccumulations are likely to occur; to make provision for draining the drip from such surfaces, and to provide a cheap, simple, easily handled'and effective arrangement of drainage trays.

Simplicity and moderate. cost are also obj ects of the invention. I

An object is to provide'a practical knock down large size refrigerator adapted to be made in a factory and to be transported in pieces to the place of use and there setup at minimum cost of labor.

Another object is to make provision for easily and conveniently cleaning the refrigerator throughout, so as to secure perfect sanitation.

Other objects, advantages and features of'.

invention may appear from the accompanying drawings, the subjoined detailed description and the appended claims. 7 The accompanying drawings invention.

Fig. 9 is an isometric view of the pan deage and cooling room 2. The doors are apthe pan 11 above which is provided an ice rack 12, uponwhich ice, not shown, is placed 1 through the icedoor 3 for the purpose of lowerlng the temperature of the cooling room. The plates 7' are shownchanneled along the inner top corners to form a seat p for the insulated top e which is constructed in a manner similar to that of the walls.

13 and 14 indicate supports below the pan 11, for arms and projections 15, 15 of drip trays 16 that are arranged in pairs below cold air chutes 17, opening downwardly through the pan. F The drip trays slope downwardly toward a central vertical plane which is indicated by the section line a2 -w in F ig.'6, and are provided at their lowest points with-drain outlets .18 through which water that has dropped through the chutes 17 .into the drip trays, may escape to a drain tray 19 that extends aslant in the central'part of the reprovided with a discharge outlet 20 that discharges through a trap 21, into a pipe22 that leads through the rear refrigerator wall a into a sewer or other suitable drain, not

shown. I

frigerator to receive the drip from said drain The cold air chutes 17 open downward from the ice chamber 1 to the cooling room 2, and consist of four rectangularly shaped openings arranged in the angles of a cross member 24 and separated by the four limbs of the cross. The top edges of the limbs of the cross are beveled and the cross is covered by sheet metal as at25 to form a. pan having the chute openings 17 Said member 24 is below the level of the ice rack 12 and above the level of the trays 16, and the lower edges of thechutesform drip skirts 26 of sheet metal from which any accumulations of moisture'ma'y drop into the drip trays 16.

The adjacent ends of the drip trays are spaced apart below the arms of the cross so as to form passages q on opposite sides of the midplane of'the cooling room, extending from front to back and each of said trays is aslant toward the mldplane of the refrigerator in opposite directions.

The drain tray 19 is U-shape inplan, and is formed with two channels 27 and'27 connected. at the lower end by a channel 28'; One end of the drain tray is provided with a: projection 29, and the bifurcated end with cross bar 30; the drain tray is suspended below the drip trays 16 by means of the projection 29 resting upon hanger member 31, and the member 30 hanging upon and overhanger clea-t 32, Each channel of the tray 19 is ar ranged-to receive the drip from two of the drain trays 16 suspended-above the drain tray 19. Drainage from tray' 19 isprovided by the means previously recited.

The ice rack 12 comprises parallel slats spaced apart thus allowing cooled air and drip from the melting ice to pass downward, and to fall upon the slanting surfaces of the pan ll from which the water flows to the chutes 17 and then over the shirts 26, from the edges of which it falls into the drip trays 16, and thence thro-ugh'drain holes 18 into the drain'tray 19, and thence out as previously described.

Barriers 33 comprising overhanging edge strips 345 fixed horizontally on upright walls 35 extending up from the edges of the pan are spaced from the front and back walls, forming therewith fines 37 through which the warmer air may flow from the cooling room and over the barriers to the cooling chamber. A water proof strip 86 is interposed between the strips 34 and the wall member 35 to prevent drip fromescapingto the outer sides of the barriers 3,3 and thence to the floor f of the a cooling room 2.

The barrier i's'made rigid by means of the vertical braces 38 one end-of eac-hof which extends beyond the lower edgeof the barrier,

and horizontal braces 38 provide means for securing said barrier to the sides 39 of the member 24 by the use of bolts or screws.

I have thus provided means for collecting and discharging the drip water from the .The air melting ice and have made provision for keeplng cooled by the ice flows down toward the pan.

The barriers 33 prevent lateral flow of air at the middle portion and the cool air flows by the trays to fill the cooling room 2 Provisions stored within the cooling roonr 2 as well as thermal radiation from the refrigerator body cause a gradual rise rin the cooling room' temperature and the warmer air will gradually'rise a-long the walls a and 0 of the refrigerator until said-warmed ail passes through the flu'es 37,- and overrthe top of the barrier 33 into'the ice box 1 as indicated by direction arrows in Fig. 6.

The walls,'top and floor are made ready at the factory and are transported to the place of use and there assembled to form the refrigerator, the floor being first laid in place and the four walls a, Z), c, d, being then erected and fastened together bylag screws 3, inserted through the studding in onev wall and screwed into the studding of the joining wall at each-corner.- I. a r

After the sides are assembled and secured by the lag screws 8 the top 6 is placed on the seat ,1? and rests thereon. V a 7 It is important that refrigerators'in which meat is stored shall be kept free from deposits of effluvia from moisture carried by the circulation from the meat to the ice and back to thecooling room, andtheice rack in this.

the cooling room practically dry. circulation is as follows: The air frigerator for thorough cleansing, thus leaving the pan free .to be thoroughlycleaned.

The baffle walls are easily accessible. and the drip and drain trays underneath, are also easily removable for cleansing so that. with proper attention the interior of the refrigerator can be keptperfectlysweet, clean and sanitary. Y v
